50 HZ PORTABLE GENERATORS G3.3A/G4.6A/GS4.6A/GS5.7A 5A
5.5 Choke
The purpose of the choke (d) is to bring the auxiliary
winding “in phase” with the main windings.
5.6 Bridge Rectifier
The bridge rectifier (e) is located on the stator housing
and is placed in a cooling air flow of the rotor. This bridge
rectifier forms a full wave rectifier to convert induced AC
current in the auxilliary winding to DC current.
5.4 Automatic Voltage Regulator (AVR)
The Automatic Voltage Regulator (AVR) (c) provides the
generator with a means of maintaining a specific voltage
regardless of load. The AVR accomplishes this by
regulating DC current from the auxiliary winding. When
the load on the generator increases, the AVR allows
additional DC current into the rotor. The additional DC
voltage allows the generator to increase output and
maintain voltage.
